Amber Rudd is facing calls to designate Iran's Revolutionary Guards as a terrorist organisation over its suppression of protesters and support for militants.

Dozens of MPs from across the Commons have backed a motion calling for the Home Secretary to include the regime's elite unit on an official list of proscribed organisations and impose sanctions on its officials.

The disclosure comes after the group, formally called the Islamic Revolutionary Guard Corps (IRGC), was deployed to put down anti-government unrest in Iran during a week of protests that left more than 20 people dead.

Of 69 MPs backing the Commons early day motion, more than 30 are Labour backbenchers - a fact likely to embarrass Jeremy Corbyn, who has since been criticised for failing to personally condemn the actions of the Iranian regime.
